RAILWAY-CROSSING.

To all whom it may concern:

Be it known that I, ANDREW HQLLINGER, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Railway-Crossings; and1' do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making a part of this specification, and to the numerals andfigures of reference marked thereon, in which- Figure 1 is a top planview showing the different parts or members of the crossing set for thepassage of trains from right to left. Fig. 2 is a section on line 22,Fig. 1. Fig. 3 is a top plan view showing the different parts or membersof the crossing set for the passage of trains from top to bottom of thefigure. Fig. 4 is a longitudinal section of one of the outerreciprocating or sliding rails. Fig. 5 is a transverse section on line55, of Fig. 8. Fig. 6 is a detached view of one pair of thereciprocating'railway crossingmembers. Fig. 7 is a transverse section online 66, Fig. 6.

The present invention has relation to railway crossings and it consistsin the novel arrangement hereinafter described and particularly pointedout in the claims.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the bed plate which is formedof suffi cient size to constitute the proper foundation for the variousmovable parts designed to be connected to said bed plate. To the bedplate 1 are also attached the adjacent ends of the main track rails 2,Which rails are connected in any convenient and well known manner.

To the bed plate 1 are independently pivoted the rock bars or levers 3and 4, to which rock bars or levers are pivotally connected theactuating bars 5 and 6; the opposite ends of said bars being pivotallyconnected to the bell cranks or levers 7 and 8. To the bell crank 7 ispivotally attached the link bar 9, said link bar being also pivotallyattached to the bell crank or lever 10. The

' bell cranks 7, 8 and 10 are held in fixed re- Speciflcation of LettersPatent.

tion common in railroad structures pertaining to railway tracks. To thebell cranks 8 and 10 are connected the tower operating rods 11 and 12,which rods may be of any desired length, and are extended to the towerand are operated by suitable levers such as are employed in theoperation of switches and railroad crossings. The tower operating leversand mechanism connected therewith is not illustrated as such parts donot pertain to or form any specific part of the present invention. Thecrossing rails 01'- members are made up of eight distinct and separateparts and constitute four separate and distinct pairs, which arenumbered 13 and 14, 15 and 16, 17 and 18, 19 and 20. The members 13, 15,17 and 19 are the outer members and the members 14:, 16, 18 and 20 arethe inner members, said inner and outer members are arranged in pairs orsets and are slidable endwise with reference to each other so that thecrossing rails proper can be lengthened and shortened by means of whicha continuous rail connection or tread is provided for the passing oftrains regardless of the direction of travel.

For the purpose of providing means for imparting reciprocating orsliding movement to each of the outer crossing rails they are eachprovided with the pivotally connected links 21, four in all and to theselinks are pivotally connected the links 22, which last mentioned linksare pivoted at their outer ends to the fixed plates 23 or theirequivalents. V For the purpose of operating the links 21 and 22 they areconnected at their inner ends to the bars 24, which bars are alsoconnected to the rock bars or levers 3 and 4 respectively.

To the inner cross rail members are pivotally connected the links 25,which are all of substantially the same construction and are connectedto the heel and oint ends of the inner rails respectively ansubstantially as shown in the drawings. To the links 25 are pivotallyconnected or joined the links 26, which links are pivoted to the fixedplates 27 or their equivalents. The various links 26 and 27 arepivotally attached to the rock bars 3 and 41, respectively, by the bars28.

It will be understood that the various links 21 and 22 and 25 and26constitute what might be termed toggle joint connections, owing to thefact that one link of each of the eight sets of links or toggle ointconnections is pivoted at a fixed point and the eight sets have theirinner ends pivotally connected together and operated by the various linkand bar connections.

It will be understood that when the tower operating rod 12 is actuatedtwo parallel sets of railroad crossing rails or members will belengthened or shortened, reference being had to the direction of motionof the tower actuating rod 12, and when the tower actuating rod 11 isactuated the opposite angled sets or members of the crossing rails ormembers will be actuated and lengthened or shortened, reference beinghad to the direction of motion of the tower actuating rod 11. Thislengthening and shortening of the various sets of crossing members orrails is brought about by the rocking movement of the rock bars orlevers 3 and 4: together with the intermediate connecting links.

It will be understood that the rocking movement of the rock bars orlevers 3 and 4 should be independent and must be independent of eachother in order that a predetermined adjustment of the railway crossingrails or members can be made. In order that a clear understanding may behad let it be assumed that at the crossing the various tracks run eastand west and north and south, and when it is desired to set the crossingfor an east or west bound train the crossing track members running eastand west are lengthened and the north and south crossing members areshortened, thereby bringing the east and west track members into such aposition, which is the lengthening one to produce a continuous rail,thereby removing the jar of the train or in other words providing roomfor the flanges of the wheels upon a passing train between the ends ofthe shortened crossing track members and the lengthened crossing trackmembers.

It will be understood that provision must be made for properly holdingthe various track crossing members in proper relative position withreference to each other and with reference to the main track rails 2,and in order to provide for thus holding the various track rail membersor crossing the retaining clips 29 are provided, which clips are of theusual construction and are secured to the bed plate 1 in any convenientand well known manner. It will be understood that these clips should beso arranged that they will permit endwise movement of the various trackrail members of the crossing.

It is well understood that the crossing rails or members should bemaintained in proper alinement with the main track rails when trainspass or move over and upon the crossing rails or members, and in orderto properly maintain the necessary alinement the inner track crossingmembers move in a true endwise or reciprocating movement, but the outerrails or track crossing members come and go or move in a lateraldirection at what might be termed their heel ends 30, but this movementis only slight and must necessarily be slight in order to maintain theproper alinement when said outer members are brought into position tocarry the wheels of a passing train. It therefore follows that the clips29 should be so adjusted wit-h reference to the outer track crossingrails or members to permit their slight lateral movement.

It will be understood that suitable connecting bolts or rivets 31 mustbe provided to properly connect the various links 2122 and 25 also thevarious links or bars which are connected to the aforesaid links.

It will be understood that by my peculiar arrangement the manner ofoperating the various members of the crossing proper a continuous trackis provided for each railway track or in other words a continuous eastand west track is provided or a contin- 26 together at their inner endsand uous north and south track is provided or any other directions. It,of course, being understood that various angles may be pro vided for,rather than a right angled crossmg.

It is well understood that railway crossings of the character to whichthis invention pertains are generally at the intersection of two or moredistinct and separate companies or systems, and it is of importance thateach companys track be substantially independ ent, or in other wordsthat there be no direct connection made as between the rails of thedifferent companies so that whatever wear there is upon the rails by thepassing of trains will be entirely upon the companys rails operating thetrains.

It will be observed as for instance in Figs. 1 and 3 the respectivetracks of the respective companies are entirely independent and thatthere is no connection as between the rails of the two companies byproviding the four pairs of sliding or adjustable rails two pairs arelocated in one companys tracks or track and the remaining two pairs inthe other companys tracks or track and that the entire wear of trains isconfined to the companys tracks used.

It will be understood that owing to a slight lateral movement of theouter crossing members 13, 15, 17 and 19 at their heel ends 30 saidouter members should be slightly angled or in other words the heelportions located at an angle to the main track rails so that the clips29 will at all times hold the heel ends of said members in properposition, or in other words that there will be no looseness as betweensaid clips and the track rails, regardless of the position of saidcrossing members. It will be understood that by forming the heel ends ofthe outer crossing members at a slight angle to the remaining portionsof said crossing members, that the clips at all times will properly holdthe heel ends" of the outer crossing members regardless of theirpositions,

Each of the outer members of the railway crossing members 13, 15, 17 and19 are provided with the beveled flange 32 upon their inner sides, thebeveled surfaces of which are located on the underside of the flange asbest illustrated in Fig. 6. The beveled flanges 32 are for the purposeof shielding the extreme pointed ends 33 of the inner railway crossingmembers 14, 16, 18 and 20. The flanges 32 are so located that when thecrossing members are expanded or set for the passage of trains theflanges 32 will come over the points 33 as best illustrated in Fig. 7This bringing over of the flanges is brought about by the slight lateralmovement of the outer railway members. It will also be understood thatthe pointed portion of the inner railway members constitutes a supportfor the outer railway crossing members, owing to the fact that thepointed ends are brought under the flanges 32 as illustrated in Fig. 6.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent, is
